US proposes to slash EV mileage ratings to meet fuel economy rules
The US Energy Department (DOE) on Monday proposed reducing electric vehicles’ (EV) mileage ratings to meet government fuel economy requirements, a move that could force automakers to sell more low-emissions cars or improve conventional models.
DOE wants to significantly revise how it calculates the petroleum-equivalent fuel economy rating for electric and plug-in electric hybrids for use in the National Highway Traffic Safety Administration’s (NHTSA) Corporate Average Fuel Economy (CAFE) program.
The current system has not been updated in more than two decades.
